Definition
Core logging is a process used in geology and engineering to assess the geological and geotechnical characteristics of rock formations. It involves visually examining and describing rock samples obtained from drilling. Technicians record information such as lithology, texture, color, fractures, and porosity. It provides valuable insights for various applications, including mining, petroleum exploration, and foundation engineering (“Core Logging Offer,” n.d.).
The Importance of Logging Core Samples
Logging core samples is an essential part of mineral exploration as it helps geologists and mining engineers determine the size, shape, and mineral composition of an ore body. This information is crucial for making informed decisions about the viability of a mining project and the best methods for extraction. Core samples also provide valuable data for geotechnical studies, resource estimates, and grade control (THE BASICS OF LOGGING CORE FOR EXPLORATION, 2019).
Core logging key components
According to (THE BASICS OF LOGGING CORE FOR EXPLORATION, 2019), the key components of logging core samples are:
- Description of lithology (the physical characteristics of the rock)
- Mineral identification and quantification
- Structural analysis
- Alteration mineral mapping
- Core recovery estimation
- Geotechnical properties
- Assaying (determining the mineral content)
